Experimental Study of Downburst Wind Flow over a Typical Three-Dimensional Hill
To achieve a comprehensive understanding of a three-dimensional (3D) wind field and the speed-up phenomenon in a downburst wind flow over a 3D hilly terrain, a succession of laboratory tests utilizing 12 hill models with cosine-squared cross-section was ...

Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to

Computational simulation of thunderstorm downbursts and associated wind turbine loads [PDF]
textWind turbines operate in a constantly changing wind environment. This requires modeling and simulation of extreme events in which the wind turbine operates and a study of associated turbine loads as part of the design practice and/or site assessment.

Abstract Accurate short‐term forecasting of thunderstorm gusts remains a major challenge in the Beijing–Tianjin–Hebei region due to limited temporal resolution, the lack of vertical velocity and thermodynamic data, and the difficulty of coupling multi‐scale features.

A simple vortex model of a thunderstorm downburst – A parametric evaluation [PDF]
Thunderstorm downbursts are short-lived, transient extreme wind events which can cause wind speeds equivalent to a category EF3 tornado (∼150mph). The complex flow field which they produce has previously been the subject of time-expensive numerical ...

Three‐Dimensional Lightning Characteristics of Severe Convective Weather in Shanghai
Using 2022–2024 ADTD data, this study analyzes 3D lightning in Shanghai's severe convection. Activity peaks in August and afternoon hours, varies by weather type, and concentrates spatially in Pudong and Chongming. Results provide key references for selecting lightning indicators in forecasting and warning systems. ABSTRACT Using ADTD three‐dimensional

Three-Dimensional Numerical Simulation of Downburst Wind Occurrded in Wuhan
Downburst is a strong downdraft generated below a cumulonimbus cloud, which hits the ground rapidly and causes significant low-level wind shear. It is a strong destructive regional weather phenomenon, which is the main reason for the transmission towers.

Investigation of Atmospheric Conditions Associated with a Storm Surge in the South-West of Iran
Severe thunderstorms are often accompanied by strong vertical air currents, temporary wind gusts, and heavy rainfall. The development of this atmospheric phenomenon over tropical shallow water zones, such as bays, can lead to intensification of ...
